Mapping the bathymetry of the Mediterranean

When most people think of the ocean, they think mostly of water, not the land that lies underneath it. But bathymetry, which is the study of water depth, is critical for understanding our coastlines. Water depth influences currents, waves, and where different marine life can live. Like topography on land, drone mapping can help collect…

Supporting green sea turtle conservation

Supporting green sea turtle conservation

Green sea turtles are an iconic species, found globally in subtropical and tropical oceans. They play an important role in maintaining the health of seagrass ecosystems and all the organisms seagrasses support. Like many larger marine creatures however, green sea turtles are under threat. By-catch from fisheries, plastic pollution and threats to nesting beaches are all contributing…

Monitoring savannah ecosystem restoration with drones

Ecosystem restoration is a key element of repairing damage to the planet and working towards a sustainable future. In theory, ecosystem restoration is simple. You simply regrow damaged or lost habitat. Saying this and doing it however, are two very different things. Ecosystem restoration is still a very new, often poorly understood science. It is…

Drone environmental monitoring: The benefits of perspective

Creating a sustainable future is a tricky balancing act of causing the smallest environmental impact for the largest positive outcome. Knowing the environmental impact of an activity, and mitigating the impact, depends heavily on good environmental monitoring. Drones are quickly becoming an indispensable tool in this space. Drone environmental monitoring offers a fast, cost effective,…

Satellite imagery and drones: Understanding fires and floods

Satellite imagery and drones: Understanding fires and floods

In the past, satellite imagery has been one of the main methods of data collection for remote sensing. As drone technology continues to advance, drones have begun to challenge satellites as a significant data collection method in many fields. Each method has its own unique advantages and disadvantages. But the combination of the two technologies…

Using drones and precision agriculture to protect the reef

Using drones and precision agriculture to protect the reef

Precision agriculture is an increasingly popular farm management strategy used to improve farm sustainability. It aims to facilitate adaptive farm and crop management based on crop health data.  By only applying treatments when needed, farmers can reduce the amount of environmentally damaging chemicals, like pesticides, used on their crops, and improve water and soil health. Advancing…

Rangeland management: A remote sensing perspective

Drones and their data processing software continue to evolve. As they do, we discover new ways to collect and process data. As the storyteller for GeoNadir, I’ve had the opportunity to talk to lots of amazing people who work with drones. This week, I spoke to Dr Jeff Gillan from the University of Arizona. He’s…

How drones are improving landslide risk management in Brazil

If you were watching international news in February, you would have heard about the devastating landslides that swept through the Brazilian city of Petrópolis. Extreme rainfall along the Serra do Mar range triggered 269 landslides. Combined with flash flooding 217 people died and more than 850 homes were destroyed.    While this natural disaster was undeniably catastrophic,…

Using Drone Data to understand Clam Reefs

Using drone images of clam reef, we estimate the amount of live tissue & model their contribution to the calcium carbonate of the reef. I have to confess that I absolutely LOVE clam chowder. I remember when I was first introduced to it at Phil’s Fish Market and Eatery in Moss Landing, California – 20…
